| Abstract: | Distinct from traditional textiles, smart textiles present new challenges to the research field and the industry. One type of smart textiles, that is, polymeric optical fiber (POF) textile performs as a flexible lighting material with great potential in illuminative smart clothing and interactive interior applications to offer a dynamic and versatile user experience and meet the increasing demands. It can be fabricated by integrating optical fibers directly into the textile structures. The design and development of weave structures and techniques offer new opportunities for POF textiles. However, weave approaches are still relatively underexplored, and the weave design system remains underdeveloped, which has restricted the development of POF textiles. Limitations still exist, such as the lack of varieties in tactile qualities and appearance features and difficulties in electronic integration. Meanwhile, the increased complexity in design, including the new design considerations for functions that are added in electronic components and multiple weft systems with unconventional materials, create new difficulties for the weave design process and production of POF textiles compared with the traditional weave design process. In this study, the weave structural design brings novel approaches and solutions to confront the design challenges in the development of POF textiles from the weaving perspectives. The systematic design model derived from the practice of the researcher also provides a means of organizing and implementing weave approaches. The study employs the practice-led research approach and explores creative weave design methods to create various forms of POF textiles. The thesis first seeks to identify weave variables to be considered and involved in future work. Diverse POF samples are developed by manipulating various weave parameters and techniques. New features of stretch and three-dimensional effect are successfully realized for POF textile, adding to its varieties in tactile qualities and appearance features. The electronic integration is improved by applying the weave technique of floating to create POF fringes during weave production. A new weave method is designed to produce touch sensitive POF textiles that include the conductive layer as an integral part of the fabric with designated sensing areas. Conductive materials are directly integrated in double weave structures along with other weft systems, including POFs and stretchable yarns. In addition, the objective evaluation for the physical properties of POF textiles is conducted. Weave structural parameters are defined, and the correlation between weave structures and the physical properties of POF textiles is examined and analyzed. Moreover, this study proposes a systematic weave design model on the basis of the researcher's own weave practice. The weave design practice, process, and knowledge yielded by this research contribute to broaden the creative scope of the POF textile development by generating new fabric features. The weave design model generated from this study will guide future studies on POF textiles from weaving perspectives. It also exhibits the potential to be further applied to other forms of e-textile development and thus help produce additional successful designs and overcome challenges. |
